tion 5 and shorter portions 6 on each side thereof with theirextremities separated from the central portion and with their medialparts joined to the middle of the central portion. To accomplish thisresult the central portion may be made straight and the shortersecondary portions deiiected and vice versa, or they may all be madestraight and parallel, as shown in Fig. 6.

The main central portion of the embossed reenforcement is preferablystraight and of constant depth and constant width for the major portionof its length, and may be deeper vor shallower or may be wider ornarrower than the unitary secondary portions of the embossedreenforcement.

The attaching pieces, which are preferably made of wood, are fitted intoand secured to the main portion of the embossment, which is preferablymade straight, so that the nailing strip will be simple to make and toapply. Lining boards are positioned perpendicularly to-the attachingpieces and nailed or otherwi se secured thereto. The attaching piecesare the same depth as the portion of the embossment in which they aresecured, the lining boards, therefore, not only bear against theattaching piece ybut also against the plate between the central portionand the other portion of the embossment.

When the reenforced plate is attached to a frame member of the car, orthe car part, the main central portion preferably overlaps the framemember and the rivet, bolts or other attaching means are positioned onthe opposite sides of the main portion of the embossment. In such anarrangement the beam stresses of the embossment are transmitted directlybv the rivets to the frame member. Furthermore, this arrangementrestrains the embossment as a beam against deflection, therebyincreasing its strength, These rivets are preferably'located inalignment with or adjacent to the terminations of the secondary portionsso that the beam stresses upon them are also transmitted directly to theframe member.

I claim:

1. In a railway car part made of a metallic plate having an embossedreenforcement formed therein comprising a central portion. and a shorterportion on each side of said central portion and partially paralleltherewith and having their extremities separated therefrom and theirmiddles joined thereto.

2. In a railway car part made of a metallic plate having an embossedreenforcement formed therein terminating within the opposite edges ofthe plate comprising a central portion, and a shorter portion on eachside of said central portion and partially parallel therewith and havingtheir extremities separated therefrom and their middles joined thereto.i

3. In a railway car part made of a metallic plate having an embossedreen'torcement formed therein comprising a central portion, and ashallower, shorter portion on each side of said central portion andpartially parallel therewith and having their extremities scparatedtherefrom and their middles joined thereto.

4f. In a railway car part made of a meta!- lic plate having an embossedreenforcement formed therein terminating within the opposite edges ofthe plate comprising a central portion` and a shallower, shorter portionon each side of said central portion and partially parallel therewithand havingtheir cxtremities separatedl therefrom and their middlesjoined thereto.

5. In a railway car part made of a metat lic plat-e having an embossedreenforcement formed therein comprising a central portion, and ashallower, narrower, shorter portion on each side of said centralportion and partially parallel therewith and having their extremitiesseparated therefrom and their middles joined thereto.

6. In a railway car part made of a metallic plate having an embossedreenforcement formed therein comprising a central portion of constantdepth, the major portion of its length, and a shorter portion on eachside of said central portion and partially parallel therewith and havingtheir extremities separated therefrom and their middles joined thereto.

7. In a railway car part made of a metallic plate having an embossedreenforcement formed therein comprising a central portion of constantdepth and constant width the major portion of its length, and a shorterportion on each side of said central portion and partially paralleltherewith and having their extremities separated therefrom and theirmiddles joined thereto 8. In a railway car part made of a metallic platehaving an embossed reenforcement formed therein comprising a. centralportion, a shorter portion on each side of said central portion havingtheir extremities separated therefrom and their middles joined thereto,attaching pieces secured within said central portion with one side flushwith the side of the plate from which the reenforcement protrudes, andlining boards secured to said attaching pieces extending perpendicularlythereto and bearing upon said attaching pieces and upon the platebetween the central portion and the other portions.

9. In a railway car, the combination of a frame member, a metallic platehaving an embossed reenforcement formed therein, comprising a centralportion, a shorter porportion on each side of said central portionhaving their extremities separated therefrom and their middles joinedthereto, said central portion overlapping said frame member,

lill

and means for attaching said plate to said trame member positioned onopposite sides ot the central portion,

l0. In a railwaj)T ear, the combination of a 'trame member, a 'metallicplate having an embossed reenforeement formed therein,

terminating within the opposite edges of the plate, comp-rising acentral portion, a shorter portion on each side of said central portionhaving their extremities separated therefrom and their middles joinedthereto, said central portion overlapping said frame member, and meansfor attaching said plate to said frame men'iber positioned on oppositesidesof the eentral portion.

ll. ln a ailway ear, the combination of a 'trame member7 a metallicplate having an embossed reen'l'oreement formed therein eomprising acentral portion, a shorter portion on each side of said central portionhaving their extremities se arated therefrom and and their middlesjoined thereto, Said central portion overlapping said frame member, andmeans for attaching said plate to said t'an'ie member positioned onopposite sides of the central portion and aligned with said shorterportions.

12. In a railway ear part made of a metallie plate having an embossedreinforcement :formed therein comprising a central portion, and allonger portion on each side of said central portion having theirextremities divverging and separated therefrom and their middles joinedthereto.
